VThis invention relatesrto a window ventilator and has for its primary object tofpro'- vide,` lin la vmannerpas A'hereinafter Vset forth,

l A far-device for use in connection with a window whereby' fresh airmay'beadmitted toa room without directk draft, thereby protectingthe health of any oneoccupying, the room and permitting the use of a'deslr or the lilre nent f toth'e window without dang-eroi? vAjlfurther object of the inventionis to* ','provide af'devicey forfthe purpose aforesaid y ,y including? as partszthereof, meansfor profy v tectlng/y the 'window sill 'from rain and snofw'rj;y '15 and means for preventing fd1rt,' dust, snow- 'and rainfrom iiowing into the room, thereby protecting the'floor coverings andy l'urnish-l l ing'swithin thefroom. f` g i .further object of the invention'is to l Zl provide faidevicefas "aforesaid provided at its top;witha` fender' forl deiiecting dust," Y snovvand the likeand for preventing I'the .same Yfrom entering the roomk at' they vtop vof @thedevice f V Q Afrth'erfobject ofthe'invention istofprof,"V

V-Witli ,hyforegoing vanddother objects in viewfthe invention consists of the novel con# struction, ,combination and, arrangement of parts as hereinafter more particularly deg scribedr andv illustratedin the accompanying drawings,y whereinvforthe purpose of illustration is shown an embodiment of my inven- I tion, but it is to bep-,understood thatvchanges, `ivariations and-modifications may be resorted to 'which fall withinfthe scopeof the invention asclaimed; f

5o therethrough# disturbancev y t strips '4 and 5, between Figure 3. is `a section taken on line 3-8 of Figure 2. i

Figure 4f, is a section taken on line 1-4 of Figure2. f f

Referring to the drawings in detail, the numerall designates the side of a window frame and 2 vand 3 respectively designate the inner and outer sills therefor. The frame sides 1 are provided with the usual vertical which a window G is slidably mounted. 4

. Seated on the inner sill 2 is a base member 7whichlis formed with a downturned flange Sybearing against the outer face of the sill 2 andV which is further formed with an angularly disposed-'portion 9 extending inwardly and'upwardly for a relatively short distance into the room. The portion 9 is bent outwardly upon itself as at 10, andthen returned as atl 11, in spaced relation to the portion ,10'7 and .forming between the portions 11 and 10 a channell12. l l v .Disposed at either side of the window frame is an end memberl, the lower edge 14 ofwhich is-formed with an inturned flange 15 for seating onthe base member 7 and the rearward edge'lof which is formed with 'an outturned flange 17 which bears against the rear face of the strip 5. The upper edge 18 of the end member 13 ismaterially longer-than the lower edge 14, whereby the forward edge-19 is; inclined inwardly from bottom to top.

.The forward edge 19 is formed with an inturned flange 2O which has a portion 21 thereof bent upon itself and returned as indicated at 22 in spaced relation to the portion 21 thereby-'providing a channel v23. The flange 20 isy of' greaterflength .than ther portions 21 o and 22 andiprojects beyond the ends of said J n 1 s portions. Likewise the'base member is In the accompanying :drawings `in. which ,f to designate like 5partsthroughoutithe same;y

of greater length than itsv angular-y disposed portion 9 and projects outwardly from either 'end of said angularly disposed portion. lRefu erence to Figure 3 will disclose 'a slight space between the horizontal planeof vthe upper edge ofthe portion 11 and the lower edge of the portionf22 as well as asimilar space between the vertical plane of the inner edge of the portion 22 and the outer end of the portion 11. Y

Carried by the base member 7 and end members 13 is an impervious plate 24, prefpreferred embodimentis as illustrated and' erably of glass, which has the lower marginal portion 25 thereof -seated within the channel 12 and which has the side marginal portion' 26 thereof seated in the channels 23. The` ference between theend members 13 has its ends overlying the forward faces of- Qtheh members 20. at the upperends ofthelatter. rlhe member `28 is disposed at the same angle of inclination as the plate 24 andjisf'ormed with a portion 29 thereof bent upon `itself and returned, as indicatedv at 30 in spaced relation to the portion 29, thereby forming avchannel 31. VhenA the top member 2 8 is Y,

in position, the'channel 31 provides a seat for the top marginal portion 32 .of the yplate 24. y

`The member 28 terminates at its, upper edge in a rearwardly` or outwardly directed shield or fender33 which curves in a returnedv arc as indicated at 34 and terminates'with,

its free edge 35 adjacent the portion 30. f The' top member 28 is of greater length than the rearwardly extending portion 33l and extendsV from either end of the' latter.

When the plate24 'is seated in they channels 12, 23 and 31, the side walls ofthe chan.

nelsy firmly grip the marginalfportions 25,

26 and 32 of the plate on both sides of the,`

latter and maintain'the Aplate in position whereby the outer ends ofthe portion' 9.ofj vthe base member 7 and also theouter endsl of the port-ionf30` of the topmember 28V arer pressed against the; outer faces of the flanges 2O at the upper and lower ends of the latter.,

In this manner the basevmember, endv members, top member and plate are held against relative displacement and an outward pressure is exerted 'on the end members to grip' the sides of the window frame. The 'flange 8 on the base member 7 holds the base ymember inpositionand also protects the finish of the sill 2 from the weather. The inclined portion 9 of the base member 7 ,together with the portions 10. and 11 prevents rain, dustand the like from entering theroom at the.

bottom of the plate 24 and thev fender or shield 33 prevents the entrance of such ele` ments intothe room at the top of the` plate 24..

It is thought that the many advantagf ofk a window ventilator in, accordance with this invention will be apparent and although the described,` yet it is tobe understood that` va-v rious changes may befmadek inX the details of construction without departing from the i spirit of the invention or the appended claims.

What I claim is: s 1. A window ventilator comprising, a base member having an angularly disposed part formed with a channel, a pair of end memscope of the bers, each having at its forward edge a flange e formed with a channel, said angularly disposed part having its end portionsoverlaplping said flanges, and a plate having marginal portions thereof disposed withinV said channels and -coacting with ythe Vwalls thereof to force said overlapping portions into frictional engagement with saidflanges for maintaining said base and end members assembled relation. f. f l, s e

V2. `A window ventila'or comprising, a hase member having an angularly'disposed' part formed with a channel, a pair of endmembers,

each having at its forwardy edge a' flange' formed with a channel, a top member formed with a channel, said topmemberand alignlarly disposed part having their endiportins overlapping said flangesfand a plate'having its marginal portion disposed said y channels and coacting with the walls thereof.

to force said overlapping ,portions intoffric-V tional engagement with said flanges for maintaining .said base, top` and end' members in assembled relation. Y

r 3.Y A window ventilator' comprising, a basek member for seating on awindo'wfsill and having an angularly disposed part formed with a channel, ay pair of end'members adapted to bear againstthe inner faces ofppposite sides of av window frame and each havingat its forward edge a flange formed with a chan;
